Create a virtual machine from a snapshot with CLI

This script creates a virtual machine from a snapshot of an OS disk.

To run this sample, install the latest version of the Azure CLI. To start, run az login to create a connection with Azure.

Samples for the Azure CLI are written for the bash shell. To run this sample in Windows PowerShell or Command Prompt, you may need to change elements of the script.

If you don't have an Azure subscription, create an Azure free account before you begin.

snapshotId=$(az snapshot show --name $snapshotName --resource-group $resourceGroupName --query [id] -o tsv)

#Create a new Managed Disks using the snapshot Id
az disk create --resource-group $resourceGroupName --name $osDiskName --sku $storageType --size-gb $diskSize --source $snapshotId 

#Create VM by attaching created managed disks as OS
az vm create --name $virtualMachineName --resource-group $resourceGroupName --attach-os-disk $osDiskName --os-type $osType
